  • Patent number: 4286503
    Abstract: A machine of the axial piston pump type used as a pump or motor including a cylinder drum mounted rotatably in a casing. Working pistons are included in the drum in working cylinders and driven as the drum rotates. The casing terminates in a tubular duct coaxial therewith that defines one of the suction and pressure openings of the machine. The tubular duct is of a diameter generally the same as that of the drum to provide for the direct flow of fluid medium to the working cylinders without undergoing a change in the direction of flow. The tubular duct terminates in a first connecting flange, and a second duct defines the other of the suction and pressure openings and terminates in a second connecting flange that extends to the side of the tubular duct.

  • Patent number: 4016771
    Abstract: A cone pulley transmission has a shaft, a first and a second pulley disc mounted on the shaft and axially displaceable thereon with respect to one another. An axial anti-friction bearing mounted on the shaft is in engagement with the first pulley disc and a bearing disc of radial orientation also mounted on the shaft. The shaft further carries an axially secured support disc adjacent that side of the bearing disc which is oriented away from the anti-friction bearing. The bearing disc is movable with respect to the support disc. Between the bearing disc and the support disc there is disposed a deformable intermediate layer which is enclosed on all sides and which is in engagement with the bearing disc and the support disc.
